While I have illustrated and described the preferred forms ofconstruction for carrying my invention into eflect, these are capable ofvariation and modification without departing from the spirit of theinvention. 7

I have shown the cut lines l8 and I9 (Figs. 1 and 10) as the preferredform of cuts to be provided in the blank, but the cuts may be variedwithout departing from my invention. Said cuts may be in the form of onestraight line extending from each end of the end wall sections or thecuts may be curved or irregular in shape, provided they extend from theends of the end wall sections and intersect the scored lines extendingfrom the adjacent corner of the bottom section to the correspondingoutside corner of'the blank at each of the four corners.

The score lines I I, H and ii are shown as being in one straight line(Figs. 1 and 10) as are score lines 13 and II, also score lines it andare shown as one straight line. These score lines are illustrated inthis way for simplicity, but in practice it may be desirable, whenfairly thick material is used, to have some of the lines slightly out ofline with each other, or at a slight angle with each other, tocompensate for the thickness of the material from which the box blank ismade in order to permit folding the walls and corners of the box to flatcondition and so that the box may be set up without binding or cramping.

Instead of applying adhesive to areas 2| (Fig. 3), 22 (Fig. 5), 23 (Fig.12) and 24 (Fig. 14), the adhesive may be applied directly to the cornersegments 8 and flap extensions I, without departing from the spirit ofmy invention.

I have shown as a preferred embodiment of my invention, that end wallcorner segments I should be secured to the end walls 4 and I at areas 2|(Fig. 3), but it is not necessary that said corner segments 8 be sosecured, because the box will be effective for many uses without beingfastened to the inside of the end walls.

Having described my invention, what I claim is:

1. A folding box comprising a bottom, upright front and rear walls andend walls, the said end walls being provided at each end thereof with aflap, and each flap having crease-hinged thereto a flap extensionsecured to the outside surface of the corresponding front or rear wall;a bellows fold element at each corner of the box being integral with aportion of the end edge of the end wall and integral'with thecorresponding end edge of the front or rear wall, one surface of saidbellows fold element being secured to the inside surface of the endwall, substantially as described.

2. A folding box comprising a bottom, upright front and rear walls andend walls, the said end walls being provided at each end thereof with aflap, and each flap having crease-hinged thereto a flap extensionsecured to the inside surface of the corresponding front or rear wall; abellows fold element at each corner of the box being integral with aportion of the end edge of the end wall and integral with thecorresponding end edge of the front or rear wall, one surface of saidbellows fold element being secured to the outside surface of the endwall, substantially as described.

3. A folding box comprising a bottom, upright front and rear walls andend walls, the said end walls being provided at each end thereof with aflap, and each flap having crease-hinged thereto a flap extensionsecured to the corresponding front or rear wall; a bellows fold elementat each comer of the box being integral with a portion of the end edgeof the end wall and integral with the corresponding end edge of thefront or rear wall, one surface of each bellows fold element beingsecured to thesurface of the corresponding end wall; the said flapextension and the bellows fold element at each corner of the box beingsecured, one to an ontside surface of the box and the other to an insidesurface of the box.
